Hold on now Todor... that failed drill was well south of the deposit and agueably in very different geology than the main zones. I imagine that Elmer's confidence in his models decreases as you move outwards from the main zone and the zillions of drills in those areas.

Even if the drill is a big fat dud, it serves geotechnical purposes and will give Elmer clues about where to go next in relation to that. Is is a big dike with all the mineralization to the west side? Take two big steps west.

Looking at this again.. I am leaning towards the southern dudd being DH 419. Elmer could have tested that chargeability 'hole' (in darkest blue) to see what was there. I am hoping that it isn't 419 which looks like it is in good chargeability.
